Amplitude Adjustment Tab
You can use an LNA or attenuator with EMxpert to increase
or decrease the power level of the signals coming from the
scanner and going to the spectrum analyzer. To activate click on
Amplification Setting or Attenuator Setting and then select the
value from the drop down menu or type the value. The displayed
value of the signal will be corrected for the value of the gain or
attenuation.
Internal Analyzer Pre-Amp:
This feature provides extra sensitivity.
It is ON by default. Turn this feature OFF if your spectrum analyzer
is not equipped with a Pre-Amp.
Analyzer Tracking Generation:
This feature will remotely turn on the tracking generator of the FieldFox
N9912A spectrum analyzer. When you run Spectral or Spectral/Spatial Scan, the tracking generator will
output a frequency that tracks the swept frequency.
